The use of carnivores as experimental models in auditory biology has led to a significant improvement regarding our understanding of the structure and function of the ear. Considering that data regarding the anatomy of the middle ear in the red fox are rare, this study aimed to describe the morphological and morphometrical features of the auditory ossicles in the red fox, as well as to provide their shape characteristics by geometric analysis. Nine adult red foxes were used in the study. The malleus, incus and stapes were extracted from the middle ear, prepared, photographed and measured using the software. For the geometric analysis, 19 landmarks were used. Following Principal Component Analysis (PCA), PC1 was found to explain approximately half of all variance (incus: 49.97%; malleus: 49.93%; stapes: 58.49%). The study demonstrated the similar anatomical organization of the auditory ossicles in line with important morphometric and basic geometric data, which can contribute to this field and add a useful perspective to the literature.
在听觉生物学中使用食肉动物作为实验模型，极大地增进了我们对耳朵结构和功能的理解。鉴于有关赤狐中耳解剖结构的数据稀少，本研究旨在描述赤狐听小骨的形态学和形态测量学特征，并通过几何分析提供其形状特征。本研究使用了9只成年赤狐。从其右耳中取出锤骨、砧骨和镫骨，进行制备、拍照，并使用软件进行测量。在几何分析中，使用了19个地标点。经过主成分分析（PCA），发现主成分1（PC1）解释了所有方差的约一半（砧骨：49.97%；锤骨：49.93%；镫骨：58.49%）。该研究证明了听小骨具有相似的解剖结构，并提供了重要的形态测量和基本几何数据，这有助于该领域的研究，并为文献增添了有用的视角。
